No. 4,772 4 Claims. (Cl. 144-27) My invention relates toa template for mortising doors and jarnbs for application thereto ofhinges, and more particularly, to a template arrangement for properlylocating, on doors and jambs, the portions thereof that are to bemortised to receive a hinge leaf.

Conventionally, carpenters, cabinet makers, and others concerned withhinging doors to jambs having to lay out on a door or jamb the portionthereof which is to be mortised to receive a hinge leaf for purposes ofhinging a door to a jamb. The portion to be mortised is usually markedin pencil and made the siZe adapted to receive the hinge leaf inquestion, which means that the hinge leaf mortise not only has to beaccurately marked out on the door or jamb, but also properly locatedwith regard to the mortise that is to receive the companion hinge leaf.Thus, much time and effort is necessarily consumed in layout work, whichmaterially increases the time required to hinge doors.

It is the principal object of this invention to provide a templatearrangement which eliminates the need for marking the door or jambportions to be mortised, and which may be used to automatically properlyindex the door and jamb portions that are to be mortised to receivecompanion hinge leaves of a hinge unit.

Another object of the invention is to provide a template for guidingrouters, which is especially adapted for mortising door edges and jambsto receive hinge leaf elements.

Still another object of the invention is to provide a door hinge leafmortising template device which is inexpensive of manufacture,convenient in use and adapted for application to a wide variety of doorhing'ng problems.

Other objects, uses and advantages will be obvious from a considerationof the following detailed description and the application drawings.

General Description Reference numeral 10 of FIGURE 1 generally indicatesa preferred embodiment of my invention which comprises a frame 12fixedly carrying track forming members 14 and 16 which slidably mountopposed jaws 18 and 20 that are to define the area of the door jamb ordoor edge which is to be mortisedi The jaws 18 and 20 are located on theforward side of the frame 12; at the rearward side of the frame 12 areslidably mounted a rigid abutment forming member 22 (see FIGURE 2) and adetachable fence 24, which is coextensive with the rigid abutmentforming member 22. A clamping foot 26 is fixed to the end of a rack 28slidably secured to the frame for operation in the plane of abutmentforming member 22.

In the illustrated form of the invention, the frame includes spacedbracing members 30 that extend crosswise of the track forming members 14ant 16 and have applied thereto measuring indicia where indicated at 32(see FIG- URE 2), the zero dimension commencing at the face 34 of trackforming member 16. The measuring indicia 32 extend between the two trackforming members and may be calibrated in inches -or any other standardof measurement.

The device 10 has associated therewith an indexing rod (see FIGURES 1and 8), which as indicated in FIG- URE l, is slidably received inaligned openings 42 formed in frame members 30 and is engaged by asuitable latch device 44 for holding the template frame in desiredpositions of adjustment with respect to the indexing rod. The indexingrod 40 is formed with the spaced annular grooves marked 1-8 in FIGURE 8and when the latch device 44 is applied to one of the grooves asindicated in FIGURE 9, the template frame will be properly located todefine a door edge or j amb portion to be mortised.

The device also includes the special adapter members 46 of FIGURE 12 foradapting the template to form door lock face plate mortises.

Specific Description Referring now to the specific structureillustrated, frame 12 comprises spaced framing members 50 which arehorizontally disposed when the device 10 is applied to a door edge orthe like, and which are rigidly fixed together by spaced crosswiseextending framing members 52, 54 and 54a, member 54a be ng fixed at itscenter to spaced framing members that are secured between member 52 andthe adjacent track forming member 16. Members 52, 54, 54a and 55 may befixed together in any suitable manner, as by screws 56. The members 54and 54a are each formed with an upstanding flange 58 between which arefixed the track bracing members 30, the latter being notched as at 60 toreceive the track forming members 14 and 16 and their slidably mountedjaws 18. The track forming members 14 and 16 may be fixed to framingmembers 50 in any suitable manner, as by welding or suitable screws orpress fitting, etc. As indicated in FIGURES 1 and 2, track formingmembers 14 and 16 are formed to define slots or grooves 62 that slidablyengage flanges 64 of jaws 18 and 20.

Jaws 18 and 20 in the illustrated embodiment each comprise a plate-likemember 66 having fixed to the front portion thereof an angle member 68.Angle member 68 has a flange 70 fixed to the respective jaws byappropriate screws 72- and a depending flange 74 that together with theinner surfaces 34 and 35 (see FIGURE 2) of the track forming membersdefine the perimeter of the mortising opening formed by device 11 Itwill be noted that this opening is a substantially closed perimeteropening and that the surfaces 34 and 35 of the track forming members asWell as surfaces 76 of the jaws are of substantially equal depths (seeFIGURE 3). Track forming members 14 and 16 each include relatively widecenter portions 78 (see FIGURE 1) to define the surfaces 34 and 35. 7

As best seen in FIGURE 1, the jaws 18 and 20 are each formed with anelongate slot 80, each of which is formed with spaced countersinkinchamfers 82 which preferably are spaced a measured distance apart and ina preferred form are struck on centers inch apart.

Chamfers 82 are provided to countersink indexing screws 84 that arereceived in slots 80 and the respective bracing members 31) for purposesof locking the jaws 13 and 20 in desired positions of adjustment.

At the rearward side of the device 10, the rigid abutment forming member22 comprises in the illustrated embodiment an elongate bar 90 fixed atits ends, as by screws 91, to blocks 92 which are slidably received overthe respective frame members 50 and carry set screws 94 for locking theminto fixed relation with frame. The rigid abutment forming member 22 isrecessed along its center portion as at 6 to define a channel shapedconfiguration that provides clearance outside of the door for the routerblade to operate in and thus defines coplanar abutment surfaces 9-8 ateach end of the member 22 or in the projections defined by the channelshaped configuration.

The fence 24 comprises a bar-like member 100 having its ends suitablynotched as at 102 for reception over the framing members 50 and carryingset screws 104 that are to engage the respective frame members 50 to fixthe fence member 100 in a desired position of adjustment. The centerportion 101 of the member 100 is disposed at one side of the fence (seeFIGURE 2a) so that when it is applied to the frame 12, it providesadequate operating clearance for the router blade.

The rack 28 has foot 26 fixed thereto as by appropriate screws 110, andfoot 26 is disposed in the plane of abutment forming member 22 (seeFIGURE 3). The rack 28 is slidably secured to the frame 12 betweenframing members 55 in any suitable manner, as by being applied betweenplates 112 and angle members 114 on one side of member 52 (see FIGUREwhich are secured together by appropriate rivets or screws 119; on theother side of member 52, the rack 28 is applied between angle members116 and 117, which are secured together by similar screws 119.

As shown in FIGURE 10, the rack 28 has formed on its outwardly facingsurface with teeth 118 which are engaged by a pawl 121 pivoted to latcharm 122 as at 124. Latch arm 122 in the illustrated embodiment ispivoted between spaced upstanding flanges 126 of the respective anglemembers 116. A U-shaped spring guard 128, comprising a spring wirehaving its ends 130 fixed to the edges 132 of the respective anglemembers 114 acts as a retainer for pawl 12%. Obviously, when the pawl120 is applied to teeth 118 and latch arm 122 pressed downwardly todispose pin 124 below pin 126, the foot Will be locked in operatingposition.

The latch 44 that cooperates with indexing rod 40 in the illustratedform comprises a tubular block 132 fixed to the track forming member 16in any suitable manner, as by appropriate screws 133 (see FIGURE 2). Thetubular housing is proportioned to slidably receive rod 48 in its bore134 (see FIGURE 9) and pivotally carries latch arm 136. Latch arm 136may include flanges 138 through which pin 140 extends to pivot same toappropriate flanges 142 fixed to the member 132. The latch arm 136includes a suitable spring 144 (see FIGURE 9) for biasing the notchedend 146 thereof into engagement with indexing rod 40. The notched end146 is formed with a semicircular groove 148 that is complementary tothe respective annular grooves 1-8 of FIG- URE 8.

The special adapter members 46 of FIGURE 12 generally compriseplate-like members 150 and 150a having fixed thereto along one edge thespaced pairs of lugs 152 and 154, as by appropriate screws 156. Theinner pair of lugs 154 may be integrally united to a connecting bar 153,and the outer lugs carry set screws for engagement with the framemembers 50 when the latter are received between the lugs of therespective pairs of lugs 152 and 154. The adapter members 46 are ofsubstantially identical construction, but the lugs 152 and 154 areapplied to opposite edges thereof, as indicated in FIGURE 12. Theadapter members 46 are applied to the device 10 with their plate-likemembers 150 and 15011 overlying the jaws 18 and 20, and preferably thejaws 18 and 20 are formed with measuring indicia where indicated at 162so that the planar edges 164 of the members 46 may be properly spacedfrom each other and from the inner surfaces of track forming members 14and 16.

Rod 40 ordinarily will be supplied in disconnectable sections and mayassume various standard lengths, de-

" pending upon the operation to which the invention is to be applied.For instance, it may be assumed that the device 10 isto be used forhinging door heights of 7 feet and 6 feet 8 inches. Consequently, rod40' Would therefore have a corresponding length and the annular groovesl-8 are provided for mortising the following (all measuring from the topof the door or jamb, as the case may be): For doors and jambs 7 feet inheight, the annular grooves marked 1 will locate the frame 12 formortising for the top hinge leaves of the door While the annular grooves2 will locate the frame 12 for mortising for the bottom hinge leaves;the annular grooves marked 6 Will locate the frame 12 for mortising forthe center hinges (assuming the standard hinging arrangement of threevertically spaced pairs of hinges), while the annular grooves 7 willlocate the frame 12 for mortising the door lock recess and strike platerecess in the jamb shown in FIG- URE 11. The annular grooves 8 areprovided for mortising rabbeted jambs, as hereinafter described more specifically.

In the embodiment illustrated, rod 40 may be also employed for mortising6'foot 8 inch doors and jambs. Thus, the grooves 1 may be used to locatethe frame 12 for mortising the top and bottom hinge leaf recesses, whilethe annular groove 3 may be employed to mortise for the center hingeleaf recesses; groove 4 will locate the frame 12 for mortising the doorlock openings and the corresponding strike plate mortises in the jambWhile annular recesses 8 are again especially adapted for use withrabbeted jambs.

Rod 49 in its illustrated form has the notches 2-8 symmetricallydisposed on either side of the center notch 3 so that either end of therod 40 may be used with equal facility.

In accordance with this invention, the rod 40 has secured to each endthereof, as by appropriate screw 180, a foot 182 which forms an abutmentmember for the end of the rod 41}. The foot 182 preferably includes apointed arm 184 that may be driven into the jamb to support frame 12,When frame 12 is applied to a jamb, as hereinafter described, and a.laterally directed seating flange 185.

Manner of Using Invention When employing the device to mortised dooredges and jambs to receive hinges, the special adapter members 46 areleft oft", while the abutment forming members 22 and fence 24 areapplied to the positions best shown in FIGURES 2 and 3.

The jaws 18 and 20 are then positioned as about to be described toconform to the size of the hinge leaf of the hinge unit for which themortising operation is to be performed. As the surface 34 of trackmember 16 starts the zero measurement of scales 32, the hinge is placedwithin the mortising opening 25 and against the surface 34, after whichthe respective screws 84 are loosened to permit the jaws 1'8 and 20 tobe set against the hinge ends and preferably an equal distance on eitherside of a center position marked by the spaced lines 170 (see FIG-URE 1) on the outwardly facing surfaces 171 of the track forming members14 and 16. Alternately, one may appropriately space jaws 18 and 20 bymeasuring one half the hinge leaf length from center notching lines 170.

The surface 172 (see FIGURE 2) of the fence 24 is then set at the pointon scales 32 which indicates the width of the hinge leaf for which themortising operation is required. Set screws 104 of the fence are thenset against frame members 59 to lock it in position and rigid abutmentforming member 22 is drawn up against the fence 24 and fixed in place byits set screws 94. Abutment forming member 22 acts as a backstop forfence 24.

Rod 40 may then be applied to its mounting body 132, which is done byinserting a section of same through body 132 and the aligned openings 42of bracing members 30.

When rod 40 has been applied to latching device 44, the latch arm 136 isapplied to the appropriate annular groove of rod 40 to dispose the frame12 in the desired position to locate a hinge leaf recess, for instance,the hinge leaf recess 190 of FIGURE 6, shown formed in edge 192 of door194. It may be assumed that the door 194 is a 7 foot door and thatrecess 190 is for the top hinge, and thus annular groove 1 would beengaged by latch arm 136 to properly position the frame 12 with re spectto the door. The outwardly extending end 195 of foot 182 of rod 40 thenmay be applied over the top 196 of the door to temporarily suspend theframe from the top of the door, with the rearward side of the framebeing placed in abutting relation with the edge 192 of the door andbetween the fence 24 and foot 26, with the door side surface 198abutting against surface 172 of fence 24. Rack member 28 is then movedin the direction of the door to bring foot 26 into engagement with theother side surface of the door, after which the latching device ofFIGURE 10 is operated to clamp the door between foot 26 and fence 24.

The template is now in position for routing out of the hinge recess, andthis may be done by a suitable router applied to the mortising opening25 defined by the jaws 18 and 20 and track forming members 14 and 16.

When the corresponding hinge leaf recess of the door jamb is to beformed, the template is removed from the door and then the foot 182 ofthe rod 40 is placed in engagement with the undersurface 200 of the doorframe header member 202, as indicated in FIGURE 5, with the pointed arm184 beating against the jamb and flange 185 at right angles to the jamb;the frame 12 may be temporarily suspended in position by tapping theedge 187 of flange 182 to drive arm 184 into the jamb. Of course, theedge 204 of the jamb 206 must be placed in engagement with the surface172 of the fence 24 and then foot 26 applied to edge 208 as beforedescribed. The hinge recess 210 of the door jamb may then be routed outby applying a suitable router to the jamb.

It will be apparent that the center and bottom hinge mortises may beformed by employing the device 10 in a similar manner, rod 40 beingemployed to measure all distances from the door header. The center hingemortises can be formed by indexing the frame 12 from either the top orthe bottom of the doorway.

In the instance where the hinge is to be applied to a rabbeted jamb, asin the showing of FIGURE 13, the frame 12 is set at the number 8 grooveto define the upper and center hinge mortising areas, and then the foot182 is placed in engagement with the lower surface 220 of header member222. The device is then operated as before described to locate and routout the recess for the hinge. The location of the corresponding hinge onthe door edge is made by moving the frame 12 down to the adjacent groove1 and then proceeding as before described.

It may be mentioned that the need for groove 8 is necessitated by therecess 224 which is formed in the edge of rabbeted jamb 226 and givesthe jamb its name. The recess 224 complements like recesses 227 formedin the header member and opposing jamb to recess the door within thedoor frame when the door is in its closed position. This arrangement isfrequently found at the exterior side of dwelling entrances. Thus,groove 8 of rod 40 is spaced from groove 1 a distance corresponding tothe depth of recess 227 of the header.

Door lock openings, such as that shown at 230 in FIGURE 11, may beproperly located by applying the adapter devices 46 to the frame 12 inthe manner indicated in FIGURE 12 and spacing them as indicated by thescales 1 62, after which set screws 160 are tightened against therespective track bracing members 30. The zero reading of these scalescommences at surface 34 of track forming member 16 which may be set atthe edge of the door by setting fence 24 to the door thickness on scales32, and since door lock openings 230 are normally centered with respectto the thickness of the door 232, the edges 164 of adapter members 46may be appropriately spaced from each other and from surface 34 (todefine the side edges of the lock mortise) by considering the Width ofthe door lock opening 230 and the distance that its sides 234 are to bespaced from the side surfaces 236 of the door. Jaws 18 and 20 are set todefine the upper and lower edges of the lock mortise.

Another way of locating the door lock mortise is to set jaws 18 and 20as above indicated and to set the fence 24 on scales 32 at a distanceequivalent to the width of the door lock mortise required plus itsspacing from the sides of the door. When the frame 12 is applied to thedoor, this automatically locates surface 34 at one side edge of thedesired door mortise, and the other side edge may be located by settingedge 164 of member a from surface 34 a distance equal to the width ofthe door mortise. In this instance, member 150 is disposed to the rightof surface 34 in the showing of FIGURE 12, but aids in providing a levelsupport for the routing tool, as members 150 and 15th; are of equalthicknesses (the tool base resting on or being pressed against members150 and 150a during operation of same). Another reason for using thedevice in this manner is that member 150 is positioned out of the Way oflock 44, which permits an indexing rod location change without having tochange the positioning of members 150 and 150a.

Member 151) in the illustrated embodiment is made sufficiently narrow sothat its edge 164 may be set back of surface 34 (to the right of FEGURE12).

The mortises for lock bolt strike plates may be located by using thesame fence setting made for the door lock mortise, removing members 150and 150a and applying frame 12 to the jamb at the same setting on indexrod 40.

The indexing rod 40 may be employed to properly locate frame 12 forforming the door lock mortise, and in the case of the illustratedembodiment, frame 12 is set at either of grooves number 7 and 4,depending on the door height (measuring from the top of the door).

I have found that fence 24 may be employed with device in all instancesof use except when applying the device to cased jambs with 4 inchrecessed margins and that when used, its depth increases the'bracingaction provided. In the instance of said cased jambs, the fence 24should be removed from the device, and the surfaces 98 (see FIGURE 2) ofabutment forming member 22 employed to clamp frame 12 in place on thejamb.

It will therefore be appreciated that I have provided a template devicefor mortising doors and jambs which materially facilitates theinstallation of doors. The device completely eliminates the need forlaying out hinge locations on doors and jambs and in effect puts themortising operation on a mass production basis. The device may be set tolocate standard hinge positions and rapidly applied to and removed fromdoors and jambs during the mortising process. The arrangement of thedevice is such that after the hinge leaves have been applied, andassembled by the usual pivot, the door will be true with its opening.

The disclosed devicecan be used for mortising hinges from sizes 1 inchto 5 inch or doors of from inch to 2%. inch in thickness and jambs offrom 1 inch to 5% inch in width. In addition to the aforementioned uses,the device may be used to mortise for flush stay bolts in doors.

The foregoing description and the drawings are given merely to explainand illustrate my invention and'the invention is not to be limitedthereto, except insofar as :he appendedclaims are so limited, sincethose skilled in the art who have my disclosure before them will be able;0 make modifications and variations therein without departing from thescope of the invention.
